The Geographical statistical classification (GSC) which includes 157,933 statistical areas, 77,773 first-level dissemination areas, and 9,458 second-level dissemination areas was established in 2012. The GSC provides an alternative way of aggregating demographic and social economic data while ensuring privacy protection. This report describes the architecture and content of GSC and illustrates how to access GSC by open data, by the web portal, and by web API services. Finally, some of the applications including dengue fever prevention, vulnerable people estimation, price information of real estate transaction, and risk analysis for soil liquefaction are demonstrated. It is expected that people get acquainted with GSC and are able to make the best use of GSC.
